A student was asked to determine the concentration of an aqueous HCl(aq) solution by titrating it with 1.13 mol/L NaOH(aq) in the presence of bromothymol blue indicator.
Since burets were not available, the student used droppers for each solution and
assumed that each drop was of equal volume. It took 26 drops of NaOH(aq) to
neutralize 20 drops of the HCl(aq) solution and to reach the bromothymol blue endpoint.
